Description

Technical Field

[0001] This utility model relates to the technical field of soybean product processing equipment, and in particular to a high-pressure cleaning and spraying device for soybeans used in natto production. Background Technology

[0002] Natto is a traditional fermented food made primarily from soybeans using Bacillus subtilis (Natto subsp. natto). It is widely popular due to its rich content of nattokinase, vitamin K2, and high-quality protein. In the production process of natto, the cleanliness of the raw soybeans directly affects the food safety, fermentation efficiency, and quality stability of the final product. During harvesting, transportation, and storage, soybeans easily accumulate dust, dirt, sand, straw fragments, insect eggs, and some microorganisms on their surface. These contaminants not only affect the appearance of the soybeans but may also carry other bacteria that compete with Bacillus subtilis for nutrients during subsequent soaking and fermentation, inhibiting the normal growth of Bacillus subtilis and leading to fermentation failure or abnormal product flavor. Furthermore, incomplete cleaning can affect the uniformity of cooking, thus affecting protein denaturation and enzymatic hydrolysis, ultimately impacting the stickiness, aroma, and texture of the natto. Ordinary spraying methods suffer from insufficient water pressure, incomplete cleaning, and the presence of blind spots.

[0003] Currently, soybeans are mostly cleaned using traditional soaking and rinsing methods or ordinary water spraying. While soaking can soften some of the dirt, it is time-consuming and can easily lead to the loss of water-soluble nutrients. In addition, if the soaking time is too long or the water quality is poor, it can actually promote the growth of microorganisms.

[0004] Therefore, it is necessary to design a high-pressure cleaning spray device for soybeans used in natto production to solve the above problems. Utility Model Content

The high-pressure water pump is fixedly connected to the cleaning chamber. A cylinder is fixedly connected to the top inside the cleaning chamber. The telescopic rod on the left side of the cylinder is fixedly connected to the right side of the nozzle. The high-pressure water pump is electrically connected to the control panel.

[0008] Preferably, the system also includes a first cover plate and a second cover plate, with the first cover plate rotatably connected to the top left side of the cleaning chamber and the second cover plate rotatably connected to the front left middle of the cleaning chamber.

[0009] Preferably, it also includes baffles, with baffles fixedly connected to both the front and rear sides of the left middle section inside the cleaning chamber.

[0010] Preferably, it also includes a magnet, with a magnet fixedly connected to the rear left side of the placement frame, and the magnet is in contact with the sliding block on the rear side.

[0011] Preferably, the device also includes a first motor and a protrusion. The first motor is fixedly connected to the middle of the left side of the cleaning chamber, and the output shaft of the first motor is fixedly connected to the protrusion on the right side. The protrusion contacts the bottom left side of the lifting frame, and the first motor is electrically connected to the control panel.

[0013] Beneficial effects: 1. This utility model uses a lifting frame with a screen. During the high-pressure spraying and vibration tumbling process, fine impurities, broken beans and dirt washed down can fall through the screen and be discharged with the water flow. Then, through the cooperation of a second motor and a screw, the placement frame moves left and right along the support track. Combined with the meshing of gears and fixed racks, the placement frame automatically flips when it moves above the ultrasonic cleaning tank, pouring the cleaned soybeans into the ultrasonic cleaning tank. The high-frequency vibration and cavitation effect further remove fine dirt and microorganisms, significantly improving the cleanliness and hygiene standards of the soybeans and greatly increasing efficiency.

[0014] 2. This utility model, through the linkage structure of high-pressure water pump, nozzle, cylinder and guide rail, can perform multi-angle and all-round powerful high-pressure washing on soybeans in the placement frame, effectively removing stubborn dirt such as mud and dust attached to the surface of soybeans, and significantly improving the cleanliness and efficiency of cleaning.

[0015] 3. This utility model uses a first motor to drive the protrusion to rotate, periodically impacting the bottom of the lifting frame. Combined with the elasticity of the telescopic spring, the lifting frame vibrates continuously up and down, causing the soybeans to tumble inside the frame. This ensures that all surfaces are thoroughly rinsed by the water flow, avoiding dead corners and improving the uniformity of cleaning.

[0016] 4. This utility model provides additional guiding force and stability for the reciprocating motion of the placement frame by setting a magnet on the rear side of the placement frame and utilizing the magnetic attraction between the magnet and the sliding block. This effectively suppresses shaking and jumping during the movement and improves the overall stability and reliability of the device. Attached Figure Description

The middle part of the water inlet pipes 31 is fixedly connected to the cleaning chamber 1, and the high-pressure water pumps 30 are installed on the right side of the water inlet pipes 31. The high-pressure water pumps 30 are fixedly connected to the cleaning chamber 1 by bolts. The cylinders 35 are fixedly connected to the top inside the cleaning chamber 1. The telescopic rod on the left side of the cylinders 35 is fixedly connected to the right side of the nozzles 33. The high-pressure water pumps 30 are electrically connected to the control panel 7.

[0027] like Figure 1 As shown, it also includes a first cover plate 2 and a second cover plate 5. The first cover plate 2 is rotatably connected to the top left side of the cleaning chamber 1, and the second cover plate 5 is rotatably connected to the front left middle part of the cleaning chamber 1.

[0028] like Figure 4 As shown, it also includes baffles 47, which are fixedly connected to both the front and rear sides of the left middle part of the cleaning chamber 1.

[0029] like Figure 5 As shown, it also includes a magnet 45. The magnet 45 is fixedly connected to the rear left side of the placement frame 40, and the magnet 45 is in contact with the rear sliding block 41.

[0030] like Figure 4 As shown, it also includes a first motor 48 and a protrusion 49. The first motor 48 is fixedly connected to the middle left side of the cleaning chamber 1 by bolts. The output shaft on the right side of the first motor 48 is fixedly connected to the protrusion 49. The protrusion 49 contacts the bottom left side of the lifting frame 43. The first motor 48 is electrically connected to the control panel 7.

[0031] like Figure 4 , Figure 6 and Figure 7 As shown, it also includes a first drain pipe 413, a first screw cap 414, a second drain pipe 62, and a second screw cap 63. The first drain pipe 413 is fixedly connected to the front of the lower left part of the cleaning chamber 1. The first screw cap 414 is threadedly connected to the front of the first drain pipe 413. The second drain pipe 62 is fixedly connected to the right side of the ultrasonic cleaning tank 60. The second drain pipe 62 passes through the cleaning chamber 1 and is exposed on the surface. The second screw cap 63 is threadedly connected to the right side of the second drain pipe 62.

[0032] When efficient and thorough cleaning of soybeans used in natto production is required, the operator opens the first cover plate 2 at the top of the cleaning chamber 1, pours the soybeans to be cleaned into the lifting frame 43 inside the placement frame 40, then closes the first cover plate 2, connects water to the water inlet pipe 31, and then starts the high-pressure water pump 30, cylinder 35, and first motor 48 through the control panel 7. The water inlet pipe 31 and the telescopic hose 32 deliver high-pressure water to the nozzle 33. The telescopic rod of the cylinder 35 pushes or pulls the nozzle 33, causing it to slide back and forth on the guide rail 34, powerfully rinsing the soybeans in the placement frame 40, effectively removing mud, dust, and other adhering substances. Simultaneously with the high-pressure spraying, the output shaft of the first motor 48 drives the protrusion 49 to rotate. Block 49 periodically strikes the bottom left side of the lifting frame 43, causing the lifting frame 43 to vibrate up and down under the action of the telescopic spring 44. This vibration promotes the continuous tumbling of soybeans inside the frame, ensuring that all surfaces are washed by the water flow. On the other hand, in conjunction with the bottom screen 430, it separates the washed-down fine impurities and broken beans, which fall down from the screen 430 with the water flow. Baffle 47 prevents natto from splashing out from the top of the placement frame 40 or falling to the bottom of the washing chamber 1 below due to tumbling, jumping, or water flow impact. The magnetic attraction between magnet 45 and sliding block 41 provides additional stability to the placement frame 40, effectively suppressing shaking during movement and improving the smoothness and reliability of the device operation.

[0033] Then, the high-pressure water pump 30, cylinder 35, and first motor 48 are turned off via control panel 7. The second cover plate 5 is opened, and an appropriate amount of clean water is injected into the ultrasonic cleaning tank 60. The second motor 411 is then started, and its output shaft drives the screw 412 to rotate. Since the sliding block 41 is threadedly engaged with the screw 412 and is limited by the support rail 42, the sliding block 41 drives the placement frame 40 to move to the right along the screw 412. During the movement, the gear 46 contacts the rack 410, and the gear 46 is driven to rotate counterclockwise, thereby driving the placement frame 40 and the lifting frame 43 to rotate counterclockwise. Natto is poured into the ultrasonic cleaning tank 60, and soybeans are sent below the surface of the cleaning tank along with the placement frame 40. Then, the second motor 411 is reversed via the control panel 7 to reset the placement frame 40 and the lifting frame 43. The ultrasonic transducer 61 is then activated via the control panel 7. The high-frequency vibration and cavitation effect generated by the ultrasonic waves can effectively remove the fine dirt from the surface of the soybeans. The ultrasonic cleaning tank 60 is then closed via the control panel 7. The first screw cap 414 and the second screw cap 63 are twisted to discharge the sewage in the cleaning chamber 1 and the cleaning tank. The first screw cap 414 and the second screw cap 63 are then tightened and reset. The second cover plate 5 is then opened to remove the cleaned soybeans. The entire cleaning process is automatically controlled by the control panel 7, which can set parameters such as cleaning time, vibration frequency, and nozzle 33 movement speed.
